Hey everyone, I finally got around to setting up my diy kit, with my main boards on the way soon, and one of the things I am most excited about is the relay modules and the other things that can be done with them. The ones on my list are my garage door opener and a sprinkler system (to be determined model/brand). First and foremost, what is everyone doing with theirs? Anything exciting? Second, I was a bit curious about how they work. I bought a multi-channel in addition to the single channel ones that came with the boards, but I cannot find much info about setup of how to use them (I suspect more documentation is incoming). Also, does each channel on the module attach to a pin, or can I use the multi-channel on a single pin? Thanks for the tips and advice.
